Dry leaves tips
Chow_13answered grow question 3 years ago
Leaf tips are a sign of nutrient burn. Your feeding to much. The dots are a deficiency showing up from to many nutrients built up in your coco. Flush with PH adjusted water( No nutrients) until the PPM of the out water shows within 100PPM of the water going in. Let it dry before watering again. Drop your nutrients down to 1200 and see if new growth shows signs. Old growth will not recover.
Happy Growing.

In coco your max ppm, ec is 800 ppm 1.6ec for photos, and 600 ppm 1.2ec for autos.your ph should be set between 6.0 and 6.5 for flower time. 6.2 to 6.3 being your best setting

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

Dealing with Nutrient Burn and Salt Build-UpI've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.

Leaf problemsMy leaves are getting yellow from the bottom, and some have burnt tips. It started when she is in flower.
I often feed Powder Feeding from Green House. PK+ (NPK: 0-30-27) and Hybrids (NPK: 15-7-22) the PH is 6.5
They say this strain wont need much nutrients but can handle more

Deficiency or excessHello colleagues,please advise me, what could it be? the tips of the leaves are sometimes lighter, and the holey leaves? I didn't find any pests in the tent. I use the AH set. Once a week I only rinse with water with enzymes. Can you think of anything?

3. Calcium Deficiency
4. Hydrogen peroxide 12% Food-grade 30/70 Mix.
Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat

She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

Possible nutrient burn ?I’m pretty sure this is nutrient burn but it’s weird because I’ve only given a tiny dose of nutrients so far. Less than a quarter of recommended dose and probably less than I’ve ever given an auto before. What do people think ? Nutrient burn ?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.
